I am wondering if anyone out there can point me
in the right direction for finding out whether there is any scientific data
quantifying the nutrient quality of home-grown or community grown vegetables
compared to those bought in the supermarkets.

I know that veggies grown and consumed fresh do
have a higher nutrient content than veggies trucked in from out of state but I
need some scientific references to use for some research that I am doing.
I am doing this so that I can bolster my argument in favor of community
supported gardening and agriculture.

If anyone has any information pointing me in the
right direction, please email me.
